Well, in my country DDR4 is already at the same price of DDR3 (even slightly cheaper in some cases) and Skylake has some nice features. Assuming the DDR4 price scenario is the same in the UK, there should be no reason to go for the 4690k.

Do yourself a favor and don't cf the 7970... it's a stutter fest. While the cards are individually awesome, the architecture of the 7970 and 7950 didn't handle cf as well as it should and caused way too much micro-stutter. I had 2x 7950 vapor x and at the the time it felt like a huge upgrade switching to an r9 290....

Correct me if I'm wrong, but in this specific benchmark, the 390 only has +1 Average fps but the "minimums" are quite lower meaning the 970 would give an overall smoother experience... And if you consider power consumption, you won't need a PSU as powerful to run the 970 making the bang for buck argument not as compelling.

Almost forgot. Usually 3SSD's in raid0 will max out what the mobo raid controller can handle in terms of performance. Adding a 4th one (example: 4x 256GB) will mainly add storage instead of performance.

Personally I would get a Swiftech H220 for the cooling CPU, and instead of a single 1TB SSD I would get 2 512GB SSD's, or even 4 256GB SSD's. Mainly because at that price you don't want to be limited by SATA 3.
 
I also agree with @Lanx about the Intel 750's instead of samsungs SSD's. And I think you would also get more out of the 980Ti's, they can be overclocked further.

Well... cost doesn't seem to be much of a problem for you so... I'd pick 4 HDD instead of 2 to make a Raid10 volume instead of Raid0 for long term storage. About the ssd... Personally I'd either prefer 2 or more ssd's in Raid0 for increased performance without increasing cost or an Intel 750 for balls to the wall performance. About the Titan X's... If you're willing to overclock, you'll probably get better performance out of 2x980ti with a good custom cooler.

I actually have a gs70 Stealth pro with one of these:

Simple, light and confusing for people who see an msi laptop with same colour scheme coming out of it 
 
Oh and the laptop fits with the sleeve.

So... I live in Portugal and I was walking around in an electronics store... when suddenly:
 
 
 

 
Wild LINUS VIDEO appeared!!
 

These are two points that cant be stressed enough. 

I like Asus's BIOS more but that's just personal preference. Honestly either one works
I'd go with the asus one

I love my Asus RoG 1440p TN screen. 

Haven't actually been to those 2... but yeah my wallet trembles in fear everytime I look at their sites

yes we need that someone make it

I've been saying this for years but we NEED a .gif of a pixelated Linus appearing as though he were a pokemon. And it must have the shiny animation as well.
 
Specifically for those rare moments when Linus turns up randomly in a thread.

You may also want to consider its follow up, the PG279Q, which is due for release soon (September/October). It's IPS, as opposed to TN, which means better colours and viewing angles, but no 3D (if that matters to you). The coating on the screen should also be much better, as the Swift came under criticism for that.

yep 

The Core M MacBook? 
For World of Warcraft I have a feeling that the experience on that specific laptop would probably be worse than what an A8 4500M/A8 6410/i5 2430M (an $800 Windows laptop or $1500 MBP would fair a bit better. I don't mind Apple but I wished that for $2,500 Apple put in a slightly better GPU in the 15" rMBP (either the 960M or AMD mobile equivalent)

That sounds dangerous...
 
That is why you need to give the gift of enlightenment to the security guards.

Security guys would be too "WTF???" for at least 10 minutes before kicking me out
